I will be installing a new Trane XV80 furnace and 2 stage scroll condenser condenser (no dedicated de-humidifier) this Saturday and reading over the manual has me a bit confused.
The installation manual for the furnace has conflicting advice regarding wiring the second stage cooling. Page 20 Note 8. Reads, For two step scroll system use Y for low speed and BK for high speed connection to the LVTB. Place a jumper between R and O and move S5-2 to the OFF position.
Page 23 of the manual, under note 7 reads "the Y2 terminal from the thermostat must be wired to the Y terminal of the furnace control for proper blower operation during cooling.

Just trying to confirm the correct wiring should be thermostat-furnace-condenser should be Y2-BK-Y2 with a jumper at the furnace between R and O with the S5 Dip switch off (S5-2 OFF means de-humidifier = installed). Im just worried because I thought BK was the proprietary variable speed blower wire that requires a specific Trane thermostat.
